Dalton theorized that atoms are indivisible, but the discovery of subatomic particles changed this theory.

Scientists now know that atoms are made up of electrons, which have a negative charge; Proton which have a positive charge; and , neutron which are neutral.

The latter two particles are found in the nucleus of the atom. it was Rutherford who discovered the nucleus of the atom.

The nucleus, which has a positive charge, occupies a very small volume of the atom. in contrast, the negatively charged electrons occupy most of the volume of the atom.

Explanation:

As per Rutherford experiment he bombarded high energy alpha particles towards the nucleus of the atom and he observed that most of the alpha particles moves out un-deviated while few shows deviation in path and very few reflected by 180 degree.

This shows the presence of very small part of atom which is positively charged

So here we can say that whole positive charge is present inside the nucleus and the negative charge of electron is around it.

technology is the collection of techniques, skills, methods, and processes used in the the merriam-webster learner's dictionary offers a definition of the term: "the use of moreover, these technologies have become so complex that entire fields more recently, modern works of science fiction such as those by philip k.
